Title: Semiconductor relay
Inventor: ENDO SHUGO
IPC: H03K17/78
Filed: 1986-03-24
Abstract: PURPOSE:To perform the turning-on/off operation with a low power signal and to attain a latch function by applying an input signal to a light emitting diode through a flip flop circuit. CONSTITUTION:Only when a signal in the high level is inputted to a flip flop circuit 9, a light emitting diode 3 is allowed to emit light or is extinguished. If the light emitting diode 3 emits light when the input signal is in the high level, light emission is continued even after the input signal falls to the low level. Consequently, a voltage is generated in a photodiode 4, which receives this light, and is applied to the gate of a FET 5, and the circuit between output terminals 6 and 7 is kept turned on. When the input signal goes to the high level again, the light emitting diode 3 stops light emission, and consequently, the circuit between output terminals 6 and 7 of the FET 5 is turned off. Thus, the circuit is turned on and off with the same signal.

Title: Semiconductor detector of radiation position
Inventor: KUMAZAWA YOSHIHIKO
IPC: G01T1/164
Filed: 1985-03-29
Abstract: PURPOSE:To stabilize the capacity of each detecting element and reduce the cost by controlling a light emitting diode with a control signal form the external and irradiating the light from the light emitting diode to the detecting element for a certain time with a bias applied. CONSTITUTION:A light emitting diode LED 7 is driven by an LED control circuit 10 controlled by the pulse signal form a pulse generator 9. The pulse generator 9 emits light for a certain time periodically. The pulse generator 9 emits light for a certain time periodically. The pulse generator 9 sends signal corresponding to this pulse signal to a position operating circuit 8 to control it so that the processing function of position operation or the like is stopped temporarily while the 1ED 7 emits light. Thus, the leak current in a substrate 1 is prevented form increasing the circuit noise to have an influence upon the capacity of the detecting element. The light is irradiated from the LED 7 while applying a high voltage bias. Since the light is irradiated from the LED 7 to the substrate 1 with the bias applied, the polarizing effect is held relatively to reduce the quantity of irradiated light.

Abstract: PURPOSE:To ensure the effective injection of the FS (frequency shift) signal for the FS signal injecting device using the thyristor serial inverter, by providing the serial switching elements which conduct only at the transmission time of the lower frequency to one side of the high-voltage capacitor in the coupling circuit. CONSTITUTION:Thyristors T1 and T2 function as serial inverter 2 by the gate signals in which gates G1 and G2 input each. And the cycle is swirched for the gate signals of gates G1 and G2 of thyristors T1 and T2 when the switching is given to the two frequencies by inverter 2 and based on the command given from FS signal output circuit 5. At the same time, the control is given to switching elements T3 and T4 which are connected in parallel to hihg-voltage capacitor C3 of the coupling circuit. Thus the conduction is secured for elements T3 and T4 only when the signal frequency of the lower side of the two signal frequencies is transmitted. In such way, the effective injection is secured for the FS signal.

IPC: H04N1/413
Filed: 1987-03-20
Abstract: PURPOSE:To eliminate irregularity of feed in the auxiliary scanning direction and occurrence of noise at the time of actuation and stoppage following interruption and reopening of reading of picture signals, by controlling the picture signal reading time so that the time can be made coincident with the time during which line encoding data read immediately before are transmitted to a circuit. CONSTITUTION:A picture signal reading section 1 sends the picture signals of a read picture to an encoding section 3 as picture signals 5. The section 3 encodes the inputted picture signals 5 and outputs the encoded picture signals as encoded data 6 and, at the same time, informs a transmitting time calculating section 4 of the encoded code quantity as a code quantity informing signal 7. The section 4 calculates that how much time is required for transmitting the encoded data through a circuit from the inputted signal 7 and circuit speed information 8 inputted from the outside of the figure. Then the transmitting time calculating section 4 informs the picture signal reading section 1 and auxiliary scanning section 2 of the calculated time by means of a reading time informing signal 9 as the reading time of the next one line or next several lines. The picture signal reading section 1 performs reading of the picture and auxiliary scanning section 2 performs auxiliary scanning in the reading time set in the unit of one line or several lines by the signal 9.

Title: Range finder
Inventor: ITO TSUGIO
IPC: G01S17/08
Filed: 1990-03-15
Abstract: PURPOSE:To accurately measure a required distance to be measured by a simple circuit by performing the circulation of a signal through a circulation circuit two or more times even when the transmission time of light through a range- finding optical path is extremely short. CONSTITUTION:Short pulse light is sent to a range-finding optical path L2 from a light emitting diode LED to be again detected by a photodetector PD. This light is again emitted through a circulation circuit constituted of a delay circuit DLAY, an amplifier A2, a waveform shaping circuit 1c, an OR circuit, a single pulse output circuit 1a and an amplifier A1. The circulation of a signal through the circulation circuit is performed two or more times (N) and the time lag of the time N(T+t) required in the range-finding optical path L2 and the time Nt required in a reference optical path L1 is taken to negate the wasteful time Nt due to the delay time in the circulation circuit and other error and a distance to be measured is calculated from the measured time NT. Since the wasteful time Nt can be selected arbitrarily, a measuring time can be shortened and a circuit can be simplified.

Abstract: PROBLEM TO BE SOLVED: To uncompress compressed image data in the case that an odd number field and an even number field of the image data are coded independently according to the respective sequence in the in-frame and inter-frame compression modes. SOLUTION: For an interval period when odd number/even number field data whose compression is effectively uncompressed (45, 46) are not found out, even number/odd number field data are used in place of the odd number/even number field data that are not found out (47-51).
